PRESSURE-ROLL RELEASE FOR CLOTHES-WRINGERS.

Patented Mar. 20, 191 '7.

Application filed October 26, 1916. Serial No. 127,893.

To all whom it may concern:

Be it known-that I, ALBERT E. HOLADAY, a citizen of the United States, residing at Naugatuck, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pressure-Roll Releases for Clothes-Wringers, of which the following is a specification, refence being bad therein to the accompanying drawing.

This invention relates to a certain new and useful improvement in a pressure roll release for clothes wringers, and consists in providing a transversely breakable top bar for the wringer frame with means for holding the abutting ends of the breakable bar in alinement in such a manner that it can be quickly released in order to allow the bar to break and move upwardly so as to release the pressure.

Another object of my invention is to pro: vide a pressure release which is exceedingly simple and cheap in construction and one in which a locking member employed for holding the sections of the breakable bar in alinement is provided with oppositely disposed buttons for rocking the locking member on its pivot in order to release the breakable bar whereby the same can be operated from either side of the wringer.

Another object of my invention is to provide a pressure release in which the sections of the transversely breakable bar are connected together by a hinge, each section having an upwardly projecting lug which is-adapted to be engaged by a locking hook of a locking member pivotally carried by one of the sections in such a manner that when the locking member is rocked in either direction, the locking hooks will bethrown out of engagement of the locking lugs to release the bar so as to allow the same to break transversely and move upwardly so that the pressure screws carried thereby will be thrown toward each other in order to release the pressure.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a side elevation of a clothes wringer partly in section showing the application of my improved construction of pressure release, the breakable bar being shown in dotted lines in raised position;

Fig. 2 is ane'nlarged longitudinal section through the breakable bar; and

Fig. 3 is a perspective view of a locking member for the sectional breakable bar.

Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing I have shown a wringer composed of a frame 1 having slotted side bars 2 in which are mounted pressure rolls 3 and 4 carried by suitable bearings, the upper bearings having spring supports 5 on which are mounted pressure springs 6 engaged by bearing plates 7 carried by a pressure bar 8. The construction thus far described is of an ordinary construction of clothes wringer and pressure means now in use.

Secured to the upper ends of the side bars 2 are caps 9 in the form of castings having overhanging lips 10 extending over the slots of the side bars and under which are adapted to be arranged the ends of a sectional top bar 11 formed of two sections pivotally connected together by a hinge as shown at 12 on the under side.

The ends of the sections of the top bar are rounded on their under sides, as clearly shown in Fig. 2, and the sections are provided with boxes 13 carrying pressure screws 14 whlch are adapted to engage the bearing plates 7 on the pressure bar 8 so as to adjust the pressure on the pressure rolls.

One of the sections of the top bar 11 is provided with a locking member 15 pivotally mounted on the end sections between the abutting ends as shown at 16, said locking member having locking hooks 17 and 18 extending in opposite directions which are adapted to engage the upwardly projecting angled ends 19 of plates 20 secured on the top of the sections of the top bar, said angle ends being rounded as shown at 21 so that the hooks 17 and 18 can move off of the angled ends in order to allow the sectional top bar to break as shown in dotted lines in Fig. 1. as when the locking member 15 is rocked on its pivot 16, the locking hooks 17 and 18 are moved transversely out of engagement with the angled ends of the plates 20. Thelocking member 15 is preferable formed of a plate having a central upwardly disposed portion which is split vertically, the portions to each side of the split being bent outwardly and downwardly to form the hooks 17 and 18, and the upper edge of the plate at each end carries a push button 22 which can be readily struck by the operator so as to rock the lock ing'member and release the sections of the top bar. v

In operation, the ends of the top ba t are forced under the overhanging lips of the caps 9, and the sections are forced together until brought into longitudinal alinement and by moving the locking member, the locking hooks 17 and 18 will engage the angled ends of the plates 20 and hold the sections in their proper position. The pressure screws are then adjusted so as to obtain the desired pressure on the pressure rolls through the medium of the pressure means, and the wringer is then in position to be operated in the ordinary manner.

In case a foreign object is drawn between the pressure rolls and it is desired to lnstantaneously release the pressure, the operator strikes one of the push buttons 22 which throws the locking hooks out of engagement with the plates and the upward pressure forces the top bar into the position as shown in dotted lines in Fig. 1 so as to release the pressure instantaneously.

I claim:

1. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a transversely breakable top bar mounted in said frame having means for adjusting said pressure means, a locking member carried by the end of one section of said top bar having oppositely disposed locking hooks and laterally projecting portions, and plates having upwardly projecting ends carried by the sections of said bar adapted to be engaged by the hooks of said locking member for holding said section in alinement.
